AIG vs 
Liberty Mutual: How Do They Compare for Cargo and Transit Insurance?
What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Liberty Mutual Business Insurance?
Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. 4,5
What Is Cargo and Transit Insurance?
Cargo coverage fits a shipper protecting goods it owns or a carrier responsible for another party’s goods. The quote needs to match who bears the loss, the shipment route and storage stops. 7,8,9,10
Key Differences in Cargo and Transit Insurance
Specific Cargo Categories and Stock Throughput
AIG lists general cargo, bulk/break-bulk, and project cargo moving over land, sea, or international borders. Liberty Mutual’s wholesale page names cargo stock-throughput but does not define which transit exposures its form covers. A distributor should request the actual wording and verify whether it applies during storage, loading, and each carrier leg instead of treating the product label as a complete coverage description. 3 6
Shipment Scope for Wholesale Businesses
AIG names importers, exporters, manufacturers, wholesalers, and distributors with international exposures. Liberty Mutual addresses wholesale and distribution businesses. That creates a clear fit question for a domestic wholesaler or a business shipping high-value project cargo: ask Liberty Mutual which cargo product applies and AIG whether the selected line is available for domestic-only movement. 3 6
